The TOPTUL 3/8 hex key wrench is designed for professional fastening, loosening and maintenance work in automotive, engineering and industrial environments.
The hex key profile is used for internal hex fasteners, with the extended form improving reach into recessed fixing points. This product is commonly used for imported equipment, American vehicles, agricultural machinery and older imperial fasteners, depending on the fastener size and equipment being serviced.
- Product code: AHBL1217

It is important to use SAE sizes on imperial fasteners rather than forcing a near-matching metric wrench, as this helps reduce rounding and fastener damage.
